Genesis 26:19-23

And Isaac’s servants digged in the valley, and found there a well of springing water.

And the herdmen of Gerar did strive with Isaac’s herdmen, saying, The water is ours: and he called the name of the well Esek; because they strove with him.

And they digged another well, and strove for that also: and he called the name of it Sitnah.

And he removed from thence, and digged another well; and for that they strove not: and he called the name of it Rehoboth; and he said, For now the LORD hath made room for us, and we shall be fruitful in the land.

And he went up from thence to Beer-sheba.
